A kind of wind-and-sand-proof apparatus of tower type solar reflection tower belongs to energy-saving field, top of tower circular arc type trussed joist arrangement of the wind-and-sand-proof apparatus along tower type solar reflection tower；It is characterized in that the wind-and-sand-proof apparatus is made of support frame, fixed link and air partition deflector；Support frame is connected and fixed bar, and air partition deflector is fixedly mounted in fixed link；Air partition deflector blows stream to each wind angle in high vacancy and forms decrease and guiding role, obstructs most of sandy soil and blows to mirror surface.The utility model, which can change, largely takes husky incoming flow wind direction; hinder direct collision and abrasion of the sand and dust to secondary reflection mirror; husky air quantity is taken by a small amount of low speed after air partition guide plate simultaneously; since the lower grains of sand of wind speed can freely be fallen under the action of self-weight; and then protect the mirror surface accuracy of secondary reflection mirror; generating efficiency is improved, the power generation maintenance cost in enterprise's later period is reduced.
Description
Technical field
The invention belongs to energy-saving field, it is mainly used for preventing high-altitude dust storm to tower type solar energy thermal power generation station mirror surface
Destruction, and in particular to it is a kind of to be broken based on secondary reflection mirror surface at the top of tower type solar energy thermal power generation station by high-altitude dust storm
It is bad, influence a kind of protective device of generating efficiency.
Background technique
Solar light-heat power-generation is that an important directions of utilization of new energy resources without any resource consumption are clean energy resourcies
First choice.It can substantially reduce the cost of solar power generation, and principal mode has slot type, tower, three kinds of systems of dish-style (disc type),
Present invention is mainly applied in a kind of fused salt tower type solar solar-thermal generating system, it is on the place of very large area equipped with perhaps
Sunlight, the secondary counter of top of tower is accurately reflected by these reflecting mirrors by more large-scale reflecting mirror (the weighed solar eyepiece of industry)
It penetrates on mirror surface, sunlight is reflected into again by secondary reflection mirror on the heat dump of tower bottom and obtains higher energy density too
Sun can be used to generate electricity.
Secondary reflection mirror is mostly installed at higher top of tower, and surface precision is higher, is generally located on the height of seventy or eighty meters
In the air, it is easy to which by the destruction of high-altitude dust storm, the sandy soil of slag inclusion can constantly hit secondary reflection mirror in high-speed air, cause
Mirror surface abrasion, seriously affects the effect of secondary reflection, not influence generating efficiency, needs the replacement secondary reflection mirror of high frequency time, makes
At the great wasting of resources, cost of electricity-generating increases, at present there is no good solutions in this phenomenon industry.
Summary of the invention
In order to solve the problems, such as that top secondary reflection mirror meets high-altitude hazards of sand storms in this tower type solar solar-thermal generating system,
Wind-and-sand-proof apparatus is arranged in tower top secondary reflection mirror surrounding in the present invention, prevents sand and dust from protecting by specific structure, shape, material
Reflecting mirror, and change simultaneously high-altitude stream to, to reduce mirror surface abrasion, protection equipment to improving generating efficiency,
A kind of wind-and-sand-proof apparatus of tower type solar reflection tower, the wind-and-sand-proof apparatus section form the taper of certain altitude
Structure, wind-and-sand-proof apparatus include support frame, fixed link, air partition deflector, are centered around secondary reflection mirror surrounding camber arrangement, Gu
It is scheduled on tower type solar photo-thermal power generation main body supporting structure column, which can blow dust storm manifold to each wind angle in high vacancy
At decrease and guiding role, most of sandy soil can be obstructed and blow to mirror surface；The device will be by biggish wind lotus in high vacancy simultaneously
It carries, in order to reduce investment manufacturing cost, air partition deflector is provided with certain percent opening, makes through the part air quantity after guide plate
Become low velocity wind, be not enough to drive sandy soil, can freely be fallen before reaching mirror surface, it, can be big after the device measure
Amplitude reduces abrasion of the high-altitude dust storm to mirror mirror, improves generating efficiency, reduces the operation cost of power generation, is not necessarily to frequently more
Change reflecting mirror.
Wind-and-sand-proof apparatus arranges that three sections of circular arcs of wind-and-sand-proof apparatus point are installed, Mei Yiduan along top of tower circular arc type trussed joist
Support frame, fixed link and air partition deflector should be installed completely on ground in advance in a pre-installation, and on support construction column
Track is preset, while multiple suspension centres are set in top of tower circular arc type trussed joist, to assembled each section of good circular arc radix saposhnikoviae
Husky device synchronizes whole promotion in orbit, after reaching the design position at top, by every section of wind-and-sand-proof apparatus two ends
It is bolted with the built-in fitting set on support construction column in advance, removes guide rail and complete installation.
When high-altitude sand and dust pass through wind-and-sand-proof apparatus with high speed incoming flow wind, it can change and largely take husky incoming flow wind side
To, direct collision and abrasion of the obstruction sand and dust to secondary reflection mirror, while husky wind is taken by a small amount of low speed after air partition deflector
Amount, since the lower grains of sand of wind speed can freely be fallen under the action of self-weight, and then protects the mirror surface accuracy of secondary reflection mirror, mentions
High generation efficiency reduces the power generation maintenance cost in enterprise's later period.

Specific embodiment
Certain tower type solar photo-thermal power generation enterprise, 80 meters of tower height, 60 meters of device diameters of tower top circle secondary reflection mirror, surrounding
By three cement support construction columns, 10 meters of secondary reflection mirror height.
Since tower top secondary reflection mirror is within the scope of 80 meters of high-altitude, wind speed is higher, and strong wind takes sand, to tower top secondary counter
It penetrates mirror mirror surface to cause to wear, needs to change the direction of incoming flow wind, or reduce wind speed reduction and take husky amount, protect secondary reflection mirror mirror
Face is not damaged, and improves generating efficiency, while reducing the replacement frequency of reflecting mirror, lowers the operation cost of enterprise's power generation.
To solve the above-mentioned problems, wind-and-sand-proof apparatus is set in tower top secondary reflection mirror surrounding, vertebral body structure, height is really
Surely will be according to specific sunlight reflected line data validation, but height setting is not less than 10 meters, and along top of tower circular arc type purlin
Frame torr beam arrangement, points of three sections circular arcs installations of wind-and-sand-proof apparatus, each section in a pre-installation should in advance ground by the support frame of device,
Fixed link and air partition deflector are installed completely, and track is preset on support construction column, while in top of tower circular arc
Multiple suspension centres are arranged in type trussed joist, synchronize whole mention in orbit to assembled each section of good circular arc wind-and-sand-proof apparatus
Rise, after reaching the design position at top, by every section of wind-and-sand-proof apparatus two ends with set on support construction column in advance
